Gutenberg没有保存我的自定义块数据

我对古腾堡来说是一个新手并且正在努力学习它 . 今天我创建了一个包含多个字段的自定义块 .

这是代码：

const { __ } = wp.i18n; // Import __() from wp.i18n
const { registerBlockType } = wp.blocks; // Import registerBlockType() from wp.blocks
const { RichText } = wp.editor;

registerBlockType( 'ss-events/event-info', {
    title: __( 'Event Info' ),
    icon: 'welcome-view-site',
    category: 'common',
    keywords: [
        __( 'Event' ),
        __( 'New Event' ),
        __( 'Manage Event' ),
    ],

    attributes: {
        teaser: {
            type: 'array',
            source: 'children',
            selector: 'p',
        },
        ev_date:{
            type: 'array',
            source: 'children',
            selector: 'p',
        },
        ev_time: {
            type: 'array',
            source: 'children',
            selector: 'p',
        },
        venue: {
            type: 'array',
            source: 'children',
            selector: 'p',
        },
        ev_nature: {
            type: 'array',
            source: 'children',
            selector: 'p',
        },
        organizer: {
            type: 'array',
            source: 'children',
            selector: 'p',
        },
    },

    edit: function( props ) {

        /* define variables */
        let teaser    = props.attributes.teaser;
        let ev_date   = props.attributes.ev_date;
        let ev_time   = props.attributes.ev_time;
        let ev_nature = props.attributes.ev_nature;
        let venue     = props.attributes.venue;
        let organizer = props.attributes.organizer;

        /* define functions */
        function onChangeTeaser( content ) {
            props.setAttributes( { teaser: content } );
        }

        function onChangeEventDate( content ) {
            props.setAttributes( { ev_date: content } );
        }

        function onChangeEventTime( content ) {
            props.setAttributes( { ev_time: content } );
        }

        function onChangeVenue( content ) {
            props.setAttributes( { venue: content } );
        }

        function onChangeEventNature( content ) {
            props.setAttributes( { ev_nature: content } );
        }

        function onChangeOrganizer( content ) {
            props.setAttributes( { organizer: content } );
        }


        return (
            <div id="ss-event-info">
                <label><b>Event Information</b></label>

                        onChange = { onChangeTeaser }
                        role = "textbox"

                </p>

                        onChage={ onChangeEventNature }
                        role="textbox"

        );
    },

    save: function( props ) {
        return (
            <RichText.content tagName="p" value={ props.attributes.teaser }/>
        );
    },
} );

当我从插入器对话框中单击它时，该块在编辑器中显示正常，但是我放在块的字段中的信息根本没有保存！

我正在使用 create-guten-block 工具来创建块结构： npx create-guten-block ss-events

古腾堡对我来说是一个全新的世界，我不知道我做错了什么 .
